Random Loot Crate Spawner
A quiet environment mod that randomly spawns loot containers in the ocean each night
Vanilla stormworks does spawn crates in the ocean by default, but this addon spawns more of them, for people who like finding them more than a few times per world.
The spawn count per night, loot lifetime, and how many of the spawned loot are chests (sinking loot) can all be configured when creating a world.
